AIR MOISTENING DEVICE Filed Sept. 30, 1932 Patented May 8, 1934 UNITEDSTATES PATENT OFFICE 4 Claims.

My invention relates to air moistening devices for homes, oiiices,factories and the like, and my main object is to provide a device ofthis kind which is in the form of a small and compact unit which can beused in conjunction with an electric lamp.

A further object of the invention is to design the novel moisteningdevice for support by the conventional electric lamp or bulb, so as toreceive heat therefrom.

A still further object of the invention is to construct the novelmoistening device in the form of an annular chamber which receives asupply of Water and disseminates the same in the form of moisture.

Another object of the invention is to provide the novel moisteningdevice with a small container for water, perfume or disinfecting liquidfor the supply of the moistening device.

An additional object of the invention is to construct the novelmoistening device of few and simple parts which are of a rugged anddurable nature.

With the above objects in view and any others that may suggestthemselves from the specification and claims to follow, a betterunderstanding of the invention may be had by reference to theaccompanying drawing, irwhich- Fig. l is a perspective View of the novelmoistening device, showing its application;

Fig. 2 is a plan view of the device; and

Fig. 3 is a section on the line 3-3 of Fig. 2.

It is a familiar fact that heat promotes the formation and dissipationof moisture, and I have chosen the common electric lamp as a source andsupport for the attachment of my moistening device. Thus, by referenceto the drawing, it is seen that the main portion of the device is ahorizontally positioned hollow ring vor chamber 10. This chamber is of asize somewhat in excess of the conventional watt or 100 Watt lamp 11used for household and factory illumination, and the chamber is intendedto be disposed about the lower part of the lamp as shown in Fig. 1.

On the inside of the chamber 10 is applied an arch 12 of sheet metal,Whose legs 12a are secured to the chamber as indicated at 12b orotherwise secured to the same. The top of the arch is expanded to form aring 12e which is of a size to fit over the narrower portion of the lamp11 and thus secure a support for the chamber 11.

The chamber 11 is formed with a number of lateral outlet pipes 13 whichcommunicate with the medial portions of external vertical tubes 14,these tubes being open at both sides.

(Cl. 21B-45) The chamber 11 also has a downwardly extending pipe 15which is fitted into and descends through a cap 16 which is inwardlythreaded to receive a small bottle 17. The pipe 15 extends down into thelower portion of the bottle and receives on the inside a wick 18 whichmay be reinforced if desired by an internal wire (not shown).

When the moistening device is to be used in a certain portion o1? aroom, that lamp 11 which is located therein is unscrewed from its socket11a and passed upwardly through the device to receive the ring 12C. Thelamp is then screwed into the socket and the current turned on. Thebottle 17 contains a lling of water, and when the chamber 10 has becomeheated by the burning lamp, the heat oi the chamber and that of the tubel5 will cause the water which is present in the latter by capillaryattraction to rise into the chamber 10 and form into a vapor. This vaporissues laterally through the pipes 13 and escapes both in upward anddownward directions through the tubes 14 by reason of the circulationcaused in the atmosphere by the heat of the lamp. Thus, the chamber 10continuously draws water from the bottle 17 and dissipates the same inthe form of moisture into the surrounding atmosphere. I have found byexperiment that a bottle containing but a few ounces of water will servefor several days, and it is an easy matter to simply unscrew the bottle17 and refill it when necessary. Obviously, a perfume or disinfectingliquid may be substituted for the plain water where a fragrance orantiseptic medium is desired for the room atmosphere.

t will be evident that the air moistening device described above is asimple, compact and sturdy attachment for the lamp. It can be made fromaluminum or other light metal for the most part in order not to imposeany strain on the lamp. It does not place anything in the way of thelight cast downwardly from the latter, so that the use of the latter forthe purpose of light may not be impaired. The assembly of the bottle 17is small and does not perceptibly interfere with the light cast by thelamp.

While I have illustrated and described the invention in the preferredform, it is evident that the same is capable of minor changes andrenements, and it is my intention to include such changes andrefinements as coming within the spirit and scope of the appendedclaims.

I claimt- 1. An air moistening device comprising an annular chamberadapted to be disposed about a 3. The structure of claim l, said liquidreservoir being removably attached to the feed tube.

4. The structure of claim l, said outlet means comprising tubes radiallyextended from the sides of the chamber, and branches of such tubesopening upwardly and downwardly.
